The object of the invention is to construct a sheet metal connection, and associated parts iin such a way as to obviate the necessity for individually soldering the parts together with a union sufficiently close and a tight to permitthc joint to be sealed and completed by dipping the parts in a bath of soldenand to thus provide a union which will not only be watertight, but will possess elements of strength and rigidity.

The elbow of the present invention comprises a tubular sect-ion 15 and an. angled portion 16. The tubular section is provided at it's free end with an inthrned flange 17. and at its connecting or interlocking end with a .reversely turned hook shaped flange 18, which latter interlocks with a reversely turned flange 19 formed on the semi-circular uniting edge of the angle shaped section 16.

the tubular The angle section 16 is of half dish shaped formation, and forms with the tubular section 15 a union along a little more than one half of the uniting edge of said tubular sec tion, the remaining portionlying in a plane above the rim of the angled section. The rim is provided with an outwardly and downwardly turned flange 20, the rim being rounded along a portion thereof most distant from the tubular section 15, which rounded portion emerges into the straight side portions 20*,Whif3l1 latter meet in abutting relation against the inner flanged end of the tubular section. t a

The connection thus connected and with the flanges interlocked -as indicated inFig.

2, is brought into registry with the lower end ofa radiator 21 or other structure with which the connection is to be ztssociated. tom or floor 22 of the radiator or the like is provided with an arched portion, which at its enlarged outer end merges into an arched aperture in the side wall 23, the two aper tures being configured to register or end with the corresponding portions of theconnection.

The margin of thebottom aperture is upturned to afford afiange 24, and the margin of the side aperture is inturned to aiiord a flange 25, which flanges 2i and 25 are adapted to interlock respectively with the flanges 20 and 18 onthe two sections of the connection, as indicated in Fig-3, which shows all of the parts in interlocking relation with one another. From this figure, it will be evi dent that the lower portion of the flange lS maintains an interlocking relation with the flange 19 up to the point where the sides of the connection come into engagement with the flange25 on the aperture inthe side Wall of theradiator, so thattherewill be no appreciable gap in the'continuity of the closure at this point; In like mannenthe flanges 20 and 241naintain an interlocked relation up to the point wherethe ends of the flange 24 abut against the upstanding portion of the tubular member 15, so that there will be no appreciable gap at this point. with the parts thus assembled; and the interlocked flanges rolled over to the figure indicated, a sufficiently close union between the parts will be afforded to ensure strength and rigidity, and to enable the joint to be ultimately sealed by dipping in a bath of solder which merely serves to fill any cracks or openings which is necessary to make the seam water tight.

The bot- The method of forming the tubular and angled sections of the connection will next.

be described. The tubular section is first pressed into the cut shaped configuration, shown in Fig. 6, having the side walls 15* and an outstanding flange 18 with an imperforate end wall 17. Thereafter a small perforation 17 is formed in the end wall.

I The next step is to furtherlengthen out the wall, as indicated in Fig. 8, which draws the m'etalaway from'the aperture and lengthens the side wall until it assumes the proport'ions indicated in. Fig. 8. This completes the formation of the tubular section with the exception of additional rolling back of the flanges 18 until they assume the hook shaped formation, illustrated in Figs. 2

Informing the angled section of the connection, :an oval shaped'blank :16 is firstpressed out-to afford a dish shaped bulge or protuberance 16 leaving a flange around the periphery. This results in a platter shaped formation having'suflicie'nt dimensions to provide for two of the-angled sections.

With the metal in this. condition, it is cut through its higher dimensions, as indicated by'dotted lines in Fig. 10, and each of the severed margins is turned upwardly to atford a flange 19, the ends of which merge with the ends of the arch shaped flange 16.

This completes the formation of the angled section with the exception of a further rollmay quickly "and easily interlock onto the apertured walls of the 'radiator'or other de-' vice'with which the connection is associated. I claim: I

1.* A connection comprising a tubular section provided at one end with an interlocking flange, and an angled section provided at one end with an interlocking flange, interlocked with a portion of the firstmentioned flange,'leaving a portion of the first mentioned "flange free from such interlocked relation, and theangled section having a nonabutting marginextending at an angle to itssaid end and being provided around its non-abutting margin with an interlocking flange, substantially as described.

' r 2.' A connection comprising a tubular section provided at one end with an interlocking flange, and an angled section provided at one end with an interlocking flange, interlocked with a portion of the first motioned flange, leaving a portion of the first mentioned flange free from such interlocked relation, and the angled section having a nonabutting margin extending at an angle to its said end and being provided around its nonabutting margin with an interlocking flange, in combination with a structure having a bottom and a side wall, there being an aperture in its bottom and a merging aperture in its side wall, each of the apertures having an interlocking flange around its margin, one of said last mentioned flanges interlocking with the non-abutting marginal flange of the angled section of the connection, and the other of said last mentioned flanges interlocking with the remaining portion of the flange on the tubular section, substantially as described.

3. A connection comprising a tubular section provided around one end with an interlocking flange, and an angled sect-ion of semidish shaped formation provided around one end with a flange interlocking with a portion of the first mentioned flange, leaving a portion of said first mentioned flange exposed, said angled section having a nonabutting portion and the margin of the nonabutting portion being provided with an outwardly turned flange extending in angled relation to the first mentioned interlocked flanges, substantially as described.

4-. A connection comprising a tubular section provided around one end with an interlocking flange, and an angled section of semidish shaped formation provided around one end with a flange interlocking with a portion of the first mentioned flange, leaving a portion of said first mentioned flange exposed, said angled section having a nonabutting portion and the margin of the nonabutting portion being provided with an outwardly turned flange extendin in an led relation to the first mentioned interloc ed flange in combination with a structure having a bottom and side wall, and provided in its bottom with an arch shaped aperture and in its side wall with a merging arch sha ed aperture, each of said apertures having around its margin an inturned flange, one of said inturned flanges being in interlocked relation with the abutting portion of the flange on the tubular section and the other of said inturned flanges being interlocked with the outwardly turned flange'around the nonabutting margin of the angled. section, substantially as described.
